                                    ComparisonOperatorService comparisonOperatorService)

Parameters:

value - the value of the argument that may or may not need coercion

expectedType - the name of the type that the function is expecting for the argument

comparisonOperatorService - the ComparisonOperatorService instance to use (if needed) for finding a StringCoercionExtension
